Next, FIG. 6 illustrates a graphical user interface 600 for generating a status code in the code generating apparatus 500 according to the embodiment of the present invention. As shown in FIG. 6, the graphical user interface 600 for generating a status code may include an ID display window 610 for selecting IDs for UI components constituting a screen and a status function for UI components. UI component state function selection window 620, condition selection window 630 for setting a condition to execute the selected state function by selecting a key / value value, and an XML format generated by combining items selected by the developer An intermediate code display window 660 in which the intermediate code of is displayed, and a final code display window 650 in which the JavaScript code for the intermediate code is displayed.

The screen for displaying the control result and status of the home network device is composed of a plurality of web UI components. For example, in the case of the screen 200 as shown in FIG. 2, a power button for turning on / off a washing machine, an operation / pause button for controlling an operation of the washing machine, a washing button, a pause button, and the like. Likewise, it includes a plurality of web UI components, each of which can be assigned a unique ID to distinguish it from other UI components.

The ID display window 610 outputs IDs of the web UI components constituting the status display screen. In FIG. 6, IDs of 'btnPower', 'btnWork', and 'txtDryTime' are output to the ID output window, and 'btnPower' is selected among them. The developer may select an ID for the component in the ID output window and then select a state function for the corresponding web UI component in the UI component state function selection window 620.

The UI component state function selection window 620 displays a state function defined for the UI component, for example, a state function that can activate or deactivate the state of the UI component. In operation 620, a state of the corresponding web UI component may be selected. In FIG. 6, the UI component state function selection window 620 outputs state functions 'gfn_setPower' and 'gfn_setDisable', respectively, and among them, a state function called 'gfn_setPower' is selected.

Thereafter, the developer sets a condition under which the selected state function can be executed by combining key / value values in the condition selection window 630. Check the check box to allow the set condition to be created in the condition creation window. In Figure 6, the condition selection window 630 has the keys 'WashCycle', 'PowerOn', 'Start' is output, the condition creation window 'WashCycle == General &&! PowerOn', 'WashCycle == Boil && Start' You can see that two conditions are created.

As described above, when a web UI component ID, a state function for each ID, and a condition under which the state function can be executed are input, the code generating apparatus 500 refers to an XML schema and generates an intermediate code for the input items. Create

When generating the intermediate code, it is preferable to generate the intermediate code according to XML (extensible Markup Language). Generating intermediate code according to XML is to make it easy to maintain, maintain and manage the developed screen later. When the intermediate code according to the XML is generated, the developer can modify the code for the already displayed status display screen.

When the intermediate code according to XML is generated by the code generating apparatus 500, the schema is generated by referring to the schema of XML. Here, the XML schema is a definition of the way the document is marked up. Class attribute, an element that can appear in an XML document, and an attribute of that element are defined. In the script code generation apparatus 500 according to an embodiment of the present invention, an XML schema used for generating intermediate code in XML format is illustrated in FIG. 7.

As shown in FIG. 7, the XML schema includes 'action' tag, 'case' tag, 'cmd' tag, 'codes' tag, 'comp' tag, 'if' tag, 'init' tag, and 'input', respectively. Tag, 'param' tag, 'states' tag, etc. are defined.

Here, the definition of 'input' tag is defined to refer to 'states' tag and 'codes' tag within 'input' tag.

However, referring to the definition of the 'states' tag in the XML schema shown in FIG. 7, the 'state' tag is referred to in the 'states' tag. However, referring to the definition of the 'state' tag in the XML schema illustrated in FIG. 7, the 'state' tag is defined to refer to the 'case' tag and the 'stateref' tag, respectively. That is, it shows that the state is defined according to the combination of key / value through the case tag and the ID of the corresponding web UI component.

In the XML schema illustrated in FIG. 7, the 'codes' tag refers to the 'comp' tag, and the 'comp' tag is defined to be created for each component ID. Also, the 'comp' tag is composed of a combination of 'com' tags, and the 'cmd' tag is defined to be composed of 'if' and 'action'.

An intermediate code generated by referring to the XML schema illustrated in FIG. 7 is illustrated in FIG. 8. As illustrated in FIG. 8, the intermediate code generated by referring to the XML schema is displayed through the intermediate code display window 660 in the graphical user interface 600 for generating the state expression code.

When the intermediate code for the items selected by the developer is generated in this way, the code generator 530 uses the intermediate code as an input and script corresponding to the input intermediate code according to the mapping information stored in the storage unit 540. Generate the code. In this case, the code generation unit 530 generates a script code coded according to a component method, which is illustrated in FIG. 8 when a part of the script code generated by the code generation unit 530 is illustrated. The script code generated by the code generator 530 is displayed on the final display code window 650 in the graphical user interface 600 for generating the state expression code.

Next, FIG. 10 is a flowchart illustrating a script code generation method according to an embodiment of the present invention.

First, the code generating apparatus 500 receives IDs of UI components constituting the status display screen 200 from a developer (S10). For example, as shown in FIG. 6, the ID btnPower is input from the component IDs output on the ID display window 610.

Next, a state function for the selected web UI component is input from the developer (S20). For example, as shown in FIG. 6, a state function called gfn_setPower is input to a component called btnPower.

Thereafter, the execution condition for the state function selected in the UI component state function selection window 620 is received through the condition selection window 630 (S30). That is, the key / value value is input through the condition selection window 630. For example, as shown in FIG. 6, as a condition under which a state function called gfn_setPower can be executed, a value of a key named WashCycle is General and a value of a key named PowerOn is false; The key / value value is entered to create a second condition where the value of the key named WashCycle is Boil and the value of the key named Start is true.

After receiving the web UI component ID, the state function for the ID, and the condition under which the selected state function can be executed by the developer, the code generating apparatus 500 refers to the XML schema, as illustrated in FIG. 8. The intermediate code of the XML format for the input items is generated (S40).

When the intermediate code of the XML format is generated by the code generating apparatus 500, the code generating unit 530 receives the intermediate code as an input and according to the mapping information table stored in the storage unit 540, is illustrated in FIG. 9. As described above, a script code of a component method corresponding to the intermediate code of the XML format is generated (S50).
